Project history
Software development and consultancy for scientific instrumentation, embedded devices and manufacturing systems. Developed C#/C++ applications, WPF interfaces, device communications, data processing and production tools. Developed embedded C/C++ for STM32/DroneCAN and Linux C++ for rapid prototyping on Raspberry Pi/CM4 using VisualGDB. Modernised legacy applications, USB integration and x86-to-x64 migration; developed WPF/SQL Server dashboards, automated testing and reporting, with LabVIEW integration.
Developed C#/.NET WPF software for the Elite Dangerous Windows launcher, supporting a game with an estimated 18 million players. Built responsive, multithreaded WPF/XAML interfaces integrating JSON web services. Supported authentication, personalised content, downloads and Steam/Epic/Oculus distribution. Collaborated with backend, QA, localisation and support teams using Jira/Confluence.
Architected scientific sensor-control, acquisition and analysis software, reusable frameworks and manufacturing systems. Developed multithreaded C++/C# frameworks for USB, RS422 and TCP/IP, WPF/SciChart visualisation and SWIG integration. Developed VisualGrad-13, MultiGrad-13 and VisualDigitiser products. Designed Grad-13 and VisualDigitiser APIs supporting C++, C#, Visual Basic and Java integration. Created a bespoke production-testing language integrating C++, SQL Server, LabVIEW and manufacturing applications.
